Why is it important to maintain the ph of blood and tissue fluids within normal limits? check all that apply
steposvetlana [31]

Enzymatic and other proteinic activity is limited by pH. 2) Slight deviations from normal pH can shut down metabolic pathways. 3) The structure and function of macromolecules are pH dependent.

<h3>How does the pH levels affect enzymes and proteins?</h3>

Enzymes, like all proteins, are polypeptidic molecules.

They need to get an accurate tridimensional structure to accomplish their function.

There is a limit of temperature and pH level at which they lose that structure and denaturalize.

<u>pH changes</u>

The most accurate configuration for the best catalytic performance depends on the charge of the lateral chains and the environmental pH.

Enzymes have ionizable chemical groups in the lateral chains of their amino acids.

Depending on the environmental pH, these groups will have a positive, negative, or neutral charge.

There is an optimum pH level at which enzymes get the best configuration to accomplish their functions.

Most enzymes are sensitive to any change in pH, which might drastically affect their activity. So every enzyme has its optimum pH level, and any slight deviations will cause the enzyme denaturalization, hence, its activity loss.

Whenever the enzyme loses its configuration, and hence, its function, the whole pathway in which it is involved is interrupted.

Options 2 and 3 are correct.

  1. Slight deviations from normal pH can shut down metabolic pathways.
  2. The structure and function of macromolecules are pH dependent.

  2. Slight deviations from normal pH can shut down metabolic pathways.
  3. The structure and function of macromolecules are pH dependent.
  4. Hormones require a blood pH of at least 77 to function,
  5. A drop in blood pH causes dehydration

The products of the light reactions of photosynthesis are ______.
Pachacha [2.7K]

The correct answer is - B) ATP and NADPH.

The products of the light reactions of the process of photosynthesis are the ATP and NADPH. The small amount of ATP produced in this process and the energy carrier NADHP are crucial for the functioning of the organisms that use the process of photosynthesis, and the reason for that is that these two are used by the organisms to create glucose, or rather sugars, in the process called the Calvin Cycle. The glucose is what these organisms use as their food, a food they they manage to make themselves, thus making them producers. If the light is missing, then the process of photosynthesis can not be performed because the formation of ATP's will be stopped, as well as the formation of NADHP, so the organisms will not be able to produce their own food.

Where does the exchange of oxygen (from the air) with carbon dioxide (from the cells) take place?
Katen [24]

<u>Answer:</u>

The Answer is <em><u>Option D. </u></em>

<em>Exchange of respiratory gases, oxygen and carbon dioxide take place in the alveoli of the lungs. Oxygen which is inhaled from the atmosphere diffuses through the walls of the alveoli and reaches to the adjacent capillaries into the red blood cells.</em>
